dB to kPa conversion method in UAN module

[huiyong dong]

Declaration:

    /**

     * Convert dB to kilopascals.

     *

     *   \f[{\rm{kPa}} = {10^{\frac{{{\rm{dB}}}}{{10}}}}\f]

     *

     * \param db Signal level in dB.

     * \return Sound pressure in kPa.

     */

    double DbToKp(double db);

Definition

double

UanPhyGen::DbToKp(double db)

{

    return std::pow(10, db / 10.0);

}

According to Sound pressure - Wikipedia, the implementation is wrong and the correct one should be std::pow(10, db / 20.0). The unit should be uPa.

Am I right?
